You wouldn't say, "these two deers showed up and started eagerly licking my dick out of nowhere." It's actually "these two deer." Likewise you don't say "deers in this forest are unusually forward" or "you have to watch out for the deers in the area who lull men into a blissful haze while they slowly become deers like them." Those sentences would be incorrect. Clear, grammatically-correct communication is important in order to make yourself understood. Of course, when your voice is reduced to a weird groaning honk, it's hard to understand much of anything that you're trying to say...
